Hi All
>From past experiance with Dolomites (same engine in 7) the input shaft will
be different and dont think about changing the input shaft and keeping the
rest as even if the input to laygear ratio were the same, chances are the
helix angle on the gear teeth is different (also found from past
experience). This is what stops the laygear cluster from lifting into place
as you near the end of making two dud boxes into one.
hope this is of some help
